/* Temporary hack to get around the thread-unsafe new/delete in cygwin
 * gcc 2.95.3.  This should all be binned at the first opportunity,
 * e.g. gcc 3.1 or sooner.
 *
 * The trick here is to do contruction via malloc(3) and then the
 * placement new operator, and destruction via an explicit call to the
 * destructor and then free(3).
